What the heck u talking about? The difficulty algorithm is trying very hard to reduce the difficulty in oder to target a 10 minute block discovery cycle. ASICs caused the network hash rate to increase and block times to go back to 30 minutes. I expect A3 to be mining 1200-1600 SC a day within a week. Right now it is mining ~1000 SC a day.

Gotta be level headed. You see people freakin out all over the place, fire selling their miners etc. By my calcs, most batch 1 A3 buyers will have ROI'd by the time the 2nd A3 batch comes online in late March. Then profits reduced from ~$30-50/day to $10-20/day assuming SC price stays around these levels.
